The present invention relates to a structure of a hot water pipe into which a heating wire is inserted. More specifically, the hot water pipe is further prevented by minimizing heat transmitted to the sealing cap of the sealing device which seals the end of the hot water pipe, thereby preventing the sealing cap from melting. It relates to the structure of a hot water pipe inserted with a heating wire that can be tightly sealed.

In general, a number of heating devices that are heated by using electricity by inserting heating wires together with heating water inside the hot water pipes have been proposed and used. (See Utility Model Registration No. 20-0405681.) The life of the heating device is determined by how to prevent the leakage of the heating water inserted therein.

A number of structures of hot water pipes for achieving the above-mentioned object have been conventionally proposed, that is, Utility Model Registration No. 20-0172037, Utility Model Registration No. 20-0326909, and Utility Application filed by the applicant. Model No. 20-2005-0035441 is known, with reference to this will be described in detail with respect to the structure of a conventional hot water pipe below.

"A" and "B" of FIG. 1 are schematic cross-sectional views showing the structure of a hot water pipe inserted with a conventional heating wire.

Referring to the drawings, referring first to "a", the heating water and the heating wire 14 are inserted into the inside of the hot water pipe 12, and an end of the sealing device 20 is provided to prevent the heating water from leaking. You can see that it is installed.

At this time, the sealing device 20 has a spiral portion formed therein, and the nut 22 and one side which is fastened so as not to be separated from the end of the hot water pipe 12 is fastened to the inner spiral portion of the nut 22. One spiral portion is formed, and on the other side, the connecting cap 23 and the sealing cap 24, 24 ′ and the sealing cap 24, 24 ′ which are fitted and fastened to the inside of the connecting piece 23 are formed. And a cap 28 for tightly fastening and a cap 28 for blocking an end of the cap nut 26.

Here, the sealing cap 24 (24 ') has a substantially rhombic shape, it can be seen that the ring washer 25 is located in the middle portion is formed in two. Since the sealing caps 24 and 24 'are fitted to prevent the leakage of the heating water, the sealing caps 24 and 24' will be formed of a rubber material having excellent elasticity. The cap nut 26, which is in close contact with 24) 24 ', will not be tightened securely.

According to the structure 10 of the conventional hot water pipe configured as described above, when power is applied to the heating wire 14 discharged to the outside, the heating water is heated by the heating wire 14 to be heated. At this time, when heating for a long time, the heating wire 14 is of course excessive heat is generated.

At this time, referring to "b", it can be seen that a part of the sealing caps 24 and 24 ′ in which the heating wires are grounded by the heated heating wires 14 melted and broken by heat. That is, since the sealing caps 24 and 24 'are elastic rubber materials, they are relatively weak to heat.

Therefore, the structure 10 of the hot water pipe has a disadvantage in that the sealing caps 24 and 24 'are melted by the excessive heat of the heating wire 14 when heated for a long time, and thus the heating water flows out.

The present invention has been made to solve the above problems, to minimize the heat transmitted to the sealing cap of the sealing device of the hot water pipe to provide a structure of the hot water pipe is inserted into the heating wire that can prevent the sealing cap melting phenomenon. do.

In order to achieve the above object, the present invention has a dual structure in which the heating wire is connected with the general wire, and the joint is configured to be placed inside the hot water pipe by applying a waterproofing solution.

Preferably, the heating wire and the general wire are connected to the connection jack so as to be connected more firmly as well as easy.

Hereinafter, with reference to the accompanying drawings will be described in more detail the structure of the hot water pipe is inserted the heating wire of the present invention.

Figure 2 is a schematic cross-sectional view showing the structural end of the hot water pipe is inserted the heating wire of the present invention, Figure 3 is a schematic cross-sectional view showing the structure of the hot water pipe is inserted according to another embodiment of the present invention.

First, referring to FIG. 2, a sealing device 20 is fastened to an end of the hot water pipe 12, and a heating wire 14 is inserted into the inside. Here, the hot water pipe 12 and the sealing device 20 of the hot water pipe 12 is the same as the structure of the conventional hot water pipe described above in the prior art.

However, it can be seen that the structure of the heating wire 14 is different. That is, it is designed to compensate for the conventional disadvantage that the sealing caps 24 and 24 'are melted by the heating of the heating wires 14, and the connection part 34 is connected by connecting the general electric wires 32 and the heating wires 14 to each other. And a waterproofing liquid 36 is applied to the connection part 34 to position the connection part 34 inside the hot water pipe 12. That is, the general wire 32 is positioned inside the sealing caps 24 and 24 ′ of the sealing device 20, and the heating wire 14 is positioned inside the hot water pipe 12. Since the heating wire 14 is located inside the hot water pipe 12, there will be no problem in heating the heating water provided in the hot water pipe 12. At this time, it is obvious that the general wire 32 extends to the outside and is connected to a power source.

Therefore, since the general wire 32 does not generate excessive heat as compared to the heating wire 14, it is possible to prevent the sealing caps 24 and 24 'formed of a relatively weak material from melting. As a result, it is possible to prevent the leakage of the heating water by preventing the breakage of the sealing device 20.

In addition, referring to Figure 3, it can be seen that the general wire 32 and the heating wire 14 are mutually connected through the connection jack 38. This will make the connection easier and more robust. Of course, the waterproof solution 36 is also applied to the connection jack 38. In this case, the connection jack 38 is generally used when connecting the wires, so a description of the structure will be omitted.

Figure 4 is a schematic cross-sectional view showing that the heating wire is installed according to an embodiment of the present invention.

Referring to the drawings, first, the heating wire 14 is inserted so as to be positioned inside the hot water pipe 12, and only the normal wire 32 connected to the heating wire 14, the sealing cap 24 of the sealing device 20 ( 24 ') Penetrate inside and draw out. Then, the sealing device 20 is coupled to the structure to seal the fastening to the hot water pipe (12).

Therefore, according to the structure 30 of the hot water pipe in which the heating wire of the present invention is inserted, the heating wire 14 is formed in a double structure connected to the general wire 32 to form a general inside the sealing cap 24, 24 ′. By allowing the wire 32 to be inserted and positioned, it is possible to minimize the heat received by the sealing caps 24 and 24 'to prevent melting. Therefore, the sealing device 20 is a useful design that can semi-permanently perform the function of sealing the hot water pipe (12).
